We all are navigators

• Satellite-based position and time determination, orientation and navigation are deeply

rooted in our daily lives.

• European GNSS Agency Market Report 2017

• 5.8 billion GNSS receivers in the market

• 8 billion expected in 2020

• ~ 1 GNSS receiver per person

• 6-7% of gross domestic product in Western countries depends on satellite navigation data?

€ 800 billion in EU

GNSS applications

3

Even small disruptions can cause severe errors!

http://www.tca.at/



GNSS interference

• Interference can be described as the effect of energy change due to the

superposition of electromagnetic waves

• Unintentional interference

• Caused by nature, other systems, multipath effects, etc.

• Intentional interference

• Jamming

• Denial of navigation service by

masking GNSS signals with noise

• Spoofing / meaconing

• Manipulation, deception, counterfeit

of GNSS PVT information

Known incidents

• Shut-down of GBAS at Newark Airport jammed

• GNSS interference attacks from North Korea against South Korea

• 117 incidents per day at Kaohsiung airport in Taiwan

• Outage of Emergency Pagers, Traffic Management Systems and ATMs in

San Diego in 2007, caused by US Navy

• Spoofing of drones and ships

• Detection and localization of GNSS interference in Graz and Vienna, Austria

Addressable market and target customers

• GIDAS is addressing private companies and public / governmental

authorities, which have the following characteristics:

• regulate safety critical infrastructures and/or operations

• operate safety critical infrastructures and/or operations

• operate systems or services where global navigation satellite system (GNSS) is key to

achieve a required high quality of service (QoS)

• The application areas of the GIDAS solution are widely spread throughout

our modern and developing societies.

Use cases

• Depending on the user needs and requirements three different stages of

expansion are available

• Static (regional) GNSS interference monitoring for safety critical GNSS applications with

high demanding requirements

• Static (regional) GNSS interference monitoring for safety critical GNSS applications with

less demanding requirements

• GNSS interference monitoring for mission critical (dynamic) GNSS applications
